Determining moment of inertia

WebMar 26, 2016 · Physics I For Dummies. In physics, when you calculate an object’s moment of inertia, you need to consider not only the mass of the object but also how the mass is distributed. For example, if two disks have the same mass but one has all the mass around the rim and the other is solid, then the disks would have different moments of inertia. WebArea Moment of Inertia. The second moment of area, more commonly known as the moment of inertia, I, of a cross section is an indication of a structural member's ability to resist bending. (Note 1) I x and I y are the moments of inertia about the x- and y- axes, respectively, and are calculated by: I x = ∫ y 2 dA. I y = ∫ x 2 dA.
